Guidelines for evaluating virtual tape libraries

摘要

A VTL appliance is a turnkey platform that includes the software that drives the VTL functionality, the server on which the software runs, and the disk array that stores the backed up data. Some vendors loosely term the VTL software and server as a VTL appliance, which fits one definition of an appliance as a dedicated-purpose server. However, we believe IT organizations interested in buying VTL appliances are best served by VTLs that incorporate storage arrays.
